The difference between a monosomy and trisomy

What is monosomy?

• Presence of an additional chromosome

• Presence of one copy of a chromosome

• Absence of a chromosome

• Two copies of each chromosome

Which chromosomal abnormality is characterized by the presence of an additional copy of a particular chromosome?

• Triploidy

• Monosomy

• Trisomy

• Tetrasomy

How is monosomy different from trisomy in terms of chromosome number?

• Monosomy has 2n+1, and trisomy has 2n-1 chromosomes

• Monosomy has 2n-1, and trisomy has 2n+1 chromosomes

• Monosomy has 2n chromosomes, and trisomy has 2n+1 chromosomes
